It's in the status bar--no status bar, no indicator. I seem to have a status bar pretty much all the time. The current version of the apk is 5.x, btw. Not all the sites listed have new versions.

I see that 5.x is the latest. I also see the status bar in "most" cases, but not when I have a book open in the Kobo reader or Overdrive. Presumably that's when one would want to know if the battery is close to dying. However, I have seen a warning pop up when the battery is supposedly down to 10%, but can't remember if it was with a book open or not. This was when I tried to charge a 50% full battery using a cheap 500ms USB charger, so I think the indication was spurious anyway. So, until Kobo fixes the battery indicator to be more reliable, would Battery Indicator Pro really be reading the battery condition independently, or what the Vox tells it? Do you see different levels in the Vox battery icon and the BIP indicator, or does the latter replace the former?
